Clothes wringers have heretofore been provided with safety devices by which the pressure of the rolls may be instantly released for any reason, such for instance, as when an operators hand is caught between the rolls. Even with the complete release of pressure there is often quite serious injury even from the weight of the parts due to the continued turningof the roll. The present invention is designed to provide a means which is responsive immediately to the action of the safety release to break the driving connection to the rolls. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows Fig. 1 shows a front elevation of a portion of the wringer, partly in section.

Fig. 2 a section on the line 2-2 in Fig. 1.

Fig. 3 an end view of the driving clutch and actuating mechanism.

Fig. 4 a section on the line 44 in Fig. 1.

Figs. 5 and 6 show detailed views of parts 25 and 39.

1 marks the base of the frame, 2 the side stiles of box form, and 3 the wringer top, the wringer top being detachable. 4 marks the lower roll, 5 the upper roll, and 6 and 7 roll shafts. The lower roll shaft is journaled in a block 8 resting on a step 9 within the stile. 10 is a bearing block for the upper roll slidingly mounted in the stile. A pressure spring 11 rests on the blocks 10.

The release device has a sleeve 12 through which an adjusting screw 13 extends and is connected to the spring by a fitting 14. The sleeve extends through an opening 16 in the fitting 15. This opening has extensions 16a. A shoulder 17 is arranged on the sleeve and operates on a cam 18 on the under-side of the fitting 15. The sleeve 12 is provided with a handle 19. When the sleeve is turned in either direction the shoulders 17 are brought 1929. Serial No. 373,251.

into register with the extensions 16a and in the Misner Reissue Patent #l5,865, June The top bar 3 is detachable. A latch 20 is mounted on a cross pin 21. The latch has a hook 22 which engages a shoulder 23 on the stile 2. The latch 20 has two sides with a connecting bar 20a. This connecting bar is in the path of the spring 11 when it is thrown up upon release. As the spring contacts the latch it detaches the hook from the shoulder 23 and releases the detachable to 3 so as to-give unlimited freedom to the lifting of the top roll.

The hook is positioned initially by an extension 24 on the latch which contacts the top wall so that as the top bar is put in place the hook will be in position to move into engagement with the shoulder 23.

A bail 25 extends around a shaft 27 and has slots 26 at its upper end through which the bolt 21 extends so that as the top bar is lifted the top roll is also lifted from the frame.

The drive shaft 6 has a radially extending pin 28 which operates in a clutch slot 29 in a clutch head 30. The head has an extending sleeve 31 which extends over a drive shaft 33. The sleeve is locked to rotate with the shaft 33 by a spline 32 but is free to slide thereon axially. The sleeve has a slot 34 and arms 35 of a lever 36 extend into this slot and by engagement with the walls of the slot throw the clutchinto and out of engagement, the clutch notch, or detent 29 being drawn away, or thrown into engagement with the pin 28. The lever 36 is pivoted at 37 on the frame and the inner end of the lever engages a bar 38 on an actuator 39. The actuator extends up along the lower bearing block 8, the bearing block having grooves 40 for guiding the actuator. The actuator has a forwardly extending plate 41 and springs 42 are tensioned between this plate and the bearing block 8. Projections to the position shown in Fig. 1 and in this position the actuator acting through the lever 36 sets the clutch and maintains the driving connection for the wringer. But when the latch is released and the top bar is lifted the bail 25 is also released and when this happens the springs 42 operate the actuator and through the lever 3.6 detach, or release the clutch. Thus automatically the operator is not only relieved of the'pressure but also of the continued rotation of the rolls.

What I claim as new is 1. In a wringer, the combination of a frame; wringer rolls in the frame; means exerting pressure on the rolls; a driving connection for the rolls; a safety release device adapted to quickly release the pressure on the rolls; and means automatically breaking the driving connection subsequent .to the release of pressure on the rolls comprising an actuator depressed through pressure on the rolls, a spring lifting the actuator on the refor the rolls; a safety release device adapted to quickly release the pressure on the rolls; and means controlling the driving means actmg upon the release of pressure on the rolls and stopping the action of the driving means sulblsequent to the release of pressure on the ro s. a
